Healthcare Industry News: Bladder Cancer
News Release - February 19, 2008
Spectrum Pharmaceuticals Receives Approval from Canadian Authorities to Expand EOquin(R) Registrational, Phase 3 Clinical Trials into CanadaIRVINE, Calif.--(HSMN NewsFeed)--Spectrum Pharmaceuticals, Inc., (Nasdaq:SPPI ) today announced that the Therapeutic Product Directorate of Health Canada has approved the trials to be conducted in Canada by issuing a No Objection Letter to Spectrum’s Clinical Trial Application for EOquin®, the Company’s drug candidate in Phase 3 clinical trials for non-invasive Bladder Cancer. Phase 3 protocols are open and currently recruiting patients in the United States. This action authorizes the initiation of clinical trials in Canada, where preparations have been underway for several months.
“An investigator’s meeting involving more than 30 urologists and their study coordinators has already been conducted in Toronto, Canada. We expect to begin enrolling patients at these sites soon,” said Rajesh C. Shrotriya, M.D., Chairman, President and CEO of Spectrum Pharmaceuticals. “More than 250 patients have already been enrolled in the United States in the first Phase 3 study, which was opened in May 2007. With the expansion of clinical trials with this large group of Canadian urologists, we expect to increase the rate of accrual in the second study, which was initiated in the U.S. in September 2007.”
The EOquin registration plan calls for two double blind, placebo-controlled, randomized Phase 3 clinical studies, each with 562 patients with Ta G1 or G2 low risk non-invasive Bladder Cancer. Patients are randomized in a one-to-one ratio to EOquin or placebo. The primary endpoint is a statistically significant difference (p<0.05) in the rate of tumor recurrence between the two treatment groups by year two. The first Phase 3 study is currently expected to complete enrollment by end of this year, and the second Phase 3 trial to be fully enrolled by mid 2009.
EOquin (apaziquone for intravesical instillation) is a drug currently being developed for the treatment of non-invasive Bladder Cancer, which is a cancer that has invaded the lining of the bladder. EOquin, an anti-cancer agent that becomes activated by reductase enzymes found in cancer cells, is formulated for administration directly into the urinary bladder. In a Phase 2 pilot study which was completed earlier this year, EOquin instilled into the bladder following surgery was well tolerated and was not absorbed in any detectable amount from the bladder wall into the bloodstream and therefore, is expected to carry a low risk of systemic toxicity, if any.
Spectrum Pharmaceuticals completed a multi-center, Phase 2 clinical trial in Europe. The results of the trial showed that EOquin was well-tolerated and produced a 67% CR (complete response) in patients, many of whom had been treated multiple times. The data from this study were presented to the FDA in early 2006.
About Bladder Cancer
The American Cancer Society estimates that 67,160 new cases of Bladder Cancer will be found in the United States. According to Globocan Data estimates, approximately 147,000 new patients will be diagnosed with Bladder Cancer in Europe during 2007. The American Cancer Society estimates that approximately 13,750 people will die of this disease in the U.S. in 2007. Globocan Data estimates more than 53,000 will die in Europe in 2007. According to these sources, at any given time, it is estimated that there are more than 500,000 patients in the U.S. and more than 935 thousand patients in Europe living with Bladder Cancer. Non-invasive Bladder Cancer accounts for 75 to 80 percent of all cases of Bladder Cancer at first diagnosis. According to Botteman et al., (PharmacoEconomics 2003), Bladder Cancer is the most expensive cancer to treat on a lifetime basis. The initial treatment of this cancer is surgical removal of the tumor. Because of the high frequency of early recurrences of the tumor, patients are usually prescribed additional therapy to prevent or delay such recurrences. This additional therapy generally consists of immunotherapy or chemotherapy drugs instilled directly into the bladder.
